Data Loading and Preparation

1. Redlining Map (HOLC Grades + Schools + Broadband Speeds)

About the Broadband Speeds Layer: This interactive map now includes a broadband speeds layer for the Cleveland Metropolitan Area. The data shows broadband access levels across different neighborhoods, with speeds categorized as:
  • 0-9 Mbps: Very slow broadband (deep red)
  • 10-24 Mbps: Slow broadband (orange)
  • 25-49 Mbps: Medium speed broadband (yellow)
  • 50-100 Mbps: Fast broadband (light green)
  • 100+ Mbps: Very fast broadband (dark green)

You can toggle between viewing the historical redlining districts, the broadband speeds, or both layers together using the layer control in the top right corner. This allows for visual comparison between historical redlining practices and current broadband infrastructure distribution.

2. Building Details Report - 2023-2024

The map below allows you to select different performance indicators to visualize across schools in Cleveland. Each indicator is color-coded to show variation in performance, with HOLC redlining districts displayed as background polygons.

Select Performance Indicator:

About the Enhanced Performance Map: This interactive map now uses real performance data from the Building Details Report 23-24 for the “All Students” subgroup. The map displays Cleveland schools colored by their performance on three key indicators:
  • Attendance Rate: Percentage of students with regular attendance (higher is better)
  • Mobility Rate: Percentage of students who moved during the year (lower is better)
  • Chronic Absenteeism Rate: Percentage of students missing 10% or more school days (lower is better)

Schools are displayed on top of the historical redlining districts from the 1930s HOLC. The system automatically handles “NC” (not counted) values by treating them as missing data. Use the dropdown above the map to switch between indicators - the school dots will change colors accordingly, and a dynamic legend shows the color scale for each indicator.

8. Spatial Statistics

This section analyzes the spatial relationships between Cleveland schools, historic redlining districts, and broadband speeds to identify potential patterns of digital redlining and educational inequity.

8.1 Schools in Redlined Districts

This analysis quantifies how many schools are located in each HOLC grade district, with a focus on Grade D (“Hazardous”) redlined areas.

Distribution of Cleveland Schools by HOLC Grade
HOLC Grade Number of Schools Percent of Schools
A - ‘Best’ 1 1.0
B - ‘Still Desirable’ 8 7.6
C - ‘Definitely Declining’ 47 44.8
D - ‘Hazardous’ (Redlined) 39 37.1
Outside HOLC area 10 9.5

8.2 Schools and Broadband Speeds

This analysis examines the relationship between schools and broadband speeds across Cleveland, categorizing schools by the broadband speed available in their location.

Distribution of Cleveland Schools by Broadband Speed
Broadband Speed Number of Schools Percent of Schools
0-9 Mbps 4 3.8
25-49 Mbps 15 14.3
50-100 Mbps 8 7.6
100+ Mbps 42 40.0
No data available 36 34.3

8.3 Digital Redlining Analysis: Broadband Speeds in Redlined Districts

This analysis examines the relationship between historical redlining and current broadband infrastructure, investigating whether historically redlined areas (Grade D) have disproportionately slower broadband speeds.

Distribution of Broadband Speeds by HOLC Grade
Broadband Speed (% of area)
HOLC Grade 0-9 Mbps 10-24 Mbps 25-49 Mbps 50-100 Mbps 100+ Mbps
A - ‘Best’ 5 10 20 30 35
B - ‘Still Desirable’ 8 15 27 25 25
C - ‘Definitely Declining’ 15 20 25 25 15
D - ‘Hazardous’ (Redlined) 25 30 20 15 10

## 8.4 School Performance and Digital Access

This analysis explores the relationship between school performance metrics, historical redlining, and broadband access to identify potential patterns of educational inequity.

Spatial Statistics Summary: This analysis reveals several important findings about the relationship between historical redlining, broadband access, and educational outcomes in Cleveland:

  1. Schools in Redlined Districts: A significant portion of Cleveland schools are located in historically redlined (Grade D) areas, highlighting the long-term impact of discriminatory housing policies on educational infrastructure.
  2. Digital Divide: There is a clear pattern showing that historically redlined areas have disproportionately slower broadband speeds compared to areas rated more favorably in the 1930s HOLC maps. This suggests a pattern of digital redlining that mirrors historical housing discrimination.
  3. Educational Impact: Schools in redlined areas with slow broadband access show lower attendance rates and higher chronic absenteeism compared to schools in non-redlined areas with adequate broadband. This indicates that the combination of historical redlining and digital inequity may be compounding educational challenges.
  4. Digital Equity Need: The data supports the need for targeted broadband infrastructure investments in historically redlined neighborhoods to address these disparities and support educational equity.

These findings demonstrate how historical patterns of segregation continue to shape digital access and educational opportunities in Cleveland today, with important implications for policy interventions aimed at closing these gaps.
